Circumference typically refers to the distance around a circle, though it may refer to the distance around any closed curve like an ellipse, though calculating the circumference of an ellipse is moderately harder than calculating the circumference of a circle. The circumference of a circle is typically solved by 
where 
represents a circle's diameter, though 
certainly works as well.
